• Conjunctivitis of the domestic fowl and an associated Rickettsia-like organism in the conjunctival epithelium 

  Coles, J.D.W.A.; DuToit, P.J. (Pretoria : The Government Printer, 1940)

  An apparently new form of conjunctivitis of the domestic fow1 has been described. No doubt the disease has been seen before and called “ocular roup”. The condition is confined to the structures of the eye. Transmission ...
• The origin of sulphur in wool. III. An improved cuprous mercaptide method for the determination of cystine in material low in cystine 

  Rossouw, S.D.; DuToit, P.J. (Pretoria : The Government Printer, 1940)

  Cystine is determined as cysteine in hydrolysates of plant or biological material of low cystine content. This method is an improvement and also more accurate than the previous one described.
• Chemical blood studies VIII. A rapid spectroscopic method for (A) the quantitative determination of haemoglobin in blood and (B) its application for the quantitative estimation of haemoglobin in milk, urine, serum or plasma and faeces 

  Roets, G.C.S.; DuToit, P.J. (Pretoria : The Government Printer, 1940)

  A spectroscopic method for the quantitative determination of the haemoglobin content of blood is described. The haematin is converted into pyridine haemochromogen and a comparison of the intensity of the 555 absorption ...
• The Senecio alkaloids. Part 2: hydrogenation, hydrolysis and structural results of isatidine 

  De Waal, H.L.; DuToit, P.J. (Pretoria : The Government Printer, 1940)

  In the first paper of this series (de Waal, 1939) the isolation and chemical properties as well as the results of the preliminary hydrolysis and of the hydrogenation of the alkaloid isatidine were recorded. This alkaloid ...
• The carotene content of some South African feeds 

  Myburgh, S.J.; DuToit, P.J. (Pretoria : The Government Printer, 1940)

  1. Carotene values are given for six well-known grasses, cut monthly from established plots under natural climatic conditions at Onderstepoort from August, 1938, to August, 1939. 2 . If the average bovine (800 lb. body ...
• The utilization by sheep of the proteins contained in the natural grazing during different seasons of the year 

  Smuts, D.B.; Marais, J.S.C.; DuToit, P.J. (Pretoria : The Government Printer, 1940)

  By means of controlled metabolism experiments it was shown that the biological value of the proteins in the natural grazing of the Transvaal varies according to the season of the year. During April the average biological ...
• The dry matter consumption of sheep on natural grazing in the Transvaal 

  Smuts, D.B.; Marais, J.S.C.; DuToit, P.J. (Pretoria : The Government Printer, 1940)

  From a study on the dry matter consumption of sheep under natural conditions of grazing, it is evident that the quantity consumed is not a factor in the loss of weight in sheep during winter. It appears from these ...
• Further studies on the amino acid deficiencies of plant proteins 

  Marais, J.S.C.; Smuts, D.B.; DuToit, P.J. (Pretoria : The Government Printer, 1940)

  By means of paired feeding tests, it has been shown that sesamemeal is deficient in cystine and that cottonseedmeal is not deficient in this amino acid. Bran and coprameal are apparently not deficient in lysine, while the ...
• A procedure for the micro determination of fluorine 

  Van der Merwe, P.K.; DuToit, P.J. (Pretoria : The Government Printer, 1940)
